Isotope-Labeled Bile Acids

Cholic acid-d₄ is the deuterium labeled Cholic acid. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion.

Chenodeoxycholic Acid-d₄ is the deuterium labeled Chenodeoxycholic Acid. Chenodeoxycholic Acid is a hydrophobic primary bile acid that activates nuclear receptors (FXR) involved in cholesterol metabolism.

Deoxycholic acid-d₄ is the deuterium labeled Deoxycholic acid. Deoxycholic acid is specifically responsible for activating the G protein-coupled bile acid receptor TGR5 that stimulates brown adipose tissue (BAT) thermogenic activity.

Glycocholic acid-d₄ is the deuterium labeled Glycocholic acid (HY-N1423). Glycocholic acid is a bile acid derivative. Glycocholic acid downregulates MDR1, Bcl-2, MRP1, MRP2 and FXR, upregulates Bax, p53, caspase-9, caspase-3, TGR5 and S1PR2. Glycocholic acid inhibits multidrug resistance and efflux pumps, induces mitochondrial apoptosis, and enhances chemosensitivity. Glycocholic acid modulates related bile acid receptor signaling. Glycocholic acid suppresses growth and conjugation of Enterobacteriaceae and increases their antibiotic susceptibility. Glycocholic acid can be used for the research of colon adenocarcinoma and cholangiocarcinoma (CCA).

Taurocholic acid-d₄ (sodium) is the deuterium labeled Taurocholic acid. Taurocholic acid (N-Choloyltaurine) is a bile acid involved in the emulsification of fats.

Lithocholic acid-d₄ is the deuterium labeled Lithocholic acid, which is a toxic secondary bile acid.

Ursodeoxycholic acid-2,2,4,4-d₄ is the deuterium labeled Ursodeoxycholic acid (HY-13771). Ursodeoxycholic acid is a secondary bile acid issued from the transformation of (cheno)deoxycholic acid by intestinal bacteria, acting as a key regulator of the intestinal barrier integrity and essential for lipid metabolism. Ursodeoxycholic acid acts as signaling molecule, exerting its effects by interacting with bile acid activated receptors, including G-protein coupled bile acid receptor 5 (TGR5, GPCR19) and the farnesoid X receptor (FXR). Ursodeoxycholic acid can be used for the research of a variety of hepatic and gastrointestinal diseases. Ursodeoxycholic acid also reduces ACE2 expression and is beneficial for reducing SARS-CoV-2 infection.

Cholic acid-d₅ is the deuterium labeled Cholic acid. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion.

Glycochenodeoxycholic acid-d₄ is the deuterium labeled Glycochenodeoxycholic acid. Glycochenodeoxycholic acid (Chenodeoxycholylglycine) is a bile acid formed in the liver from chenodeoxycholate and glycine. It acts as a detergent to solubilize fats for absorption and is itself absorbed. Glycochenodeoxycholic acid (Chenodeoxycholylglycine) induces hepatocyte apoptosis.

Glycodeoxycholic acid-d₄ is the deuterium labeled Glycodeoxycholic Acid. Glycodeoxycholic Acid is an endogenous metabolite.

Cholic acid-¹³C is the ¹³C-labeled Cholic acid. Cholic acid is a major primary bile acid produced in the liver and usually conjugated with glycine or taurine. It facilitates fat absorption and cholesterol excretion.

Glycoursodeoxycholic acid-d₄ (Ursodeoxycholylglycine-d₄) is the deuterium labeled Glycoursodeoxycholic acid. Glycoursodeoxycholic acid, a acyl glycine and a bile acid-glycine conjugate, is a metabolite of ursodeoxycholic acid.

Taurochenodeoxycholic acid-d₄ (sodium) is the deuterium labeled Taurochenodeoxycholic acid. Taurochenodeoxycholic acid (12-Deoxycholyltaurine) is one of the main bioactive substances of animals' bile acid. Taurochenodeoxycholic acid induces apoptosis and shows obvious anti-inflammatory and immune regulation properties.

Chenodeoxycholic acid-d₅ is the deuterium labeled Chenodeoxycholic Acid. Chenodeoxycholic Acid is a hydrophobic primary bile acid that activates nuclear receptors (FXR) involved in cholesterol metabolism.

Deoxycholic acid-¹³C is the ¹³C-labeled Deoxycholic acid. Deoxycholic acid is specifically responsible for activating the G protein-coupled bile acid receptor TGR5 that stimulates brown adipose tissue (BAT) thermogenic activity.

Taurocholic acid-d₄ is deuterium labeled Taurocholic acid. Taurocholic acid (N-Choloyltaurine) is a bile acid involved in the emulsification of fats.

Glycolithocholic acid-d₄ is the deuterium labeled Glycolithocholic acid. Glycolithocholic acid, an endogenous metabolite, is a glycine-conjugated secondary bile acid and can be used to diagnose ulcerative colitis (UC), non-alcoholic steatohepatitis (NASH) and primary sclerosing cholangitis (PSC) .

Taurochenodeoxycholic acid-d₅ (sodium) is the deuterium labeled Taurochenodeoxycholic acid sodium. Taurochenodeoxycholic acid sodium salt (12-Deoxycholyltaurine sodium salt) is one of the main bioactive substances of animals' bile acid. Taurochenodeoxycholic acid induces apoptosis and shows obvious anti-inflammatory and immune regulation properties.

Deoxycholic acid-d₅ is the deuterium labeled Deoxycholic acid. Deoxycholic acid is specifically responsible for activating the G protein-coupled bile acid receptor TGR5 that stimulates brown adipose tissue (BAT) thermogenic activity.

Chenodeoxycholic acid-¹³C is the ¹³C-labeled Chenodeoxycholic Acid. Chenodeoxycholic Acid is a hydrophobic primary bile acid that activates nuclear receptors (FXR) involved in cholesterol metabolism.
